Description
Technical field
The present invention relates to be used for the device of the advective cooling of motor vehicle powertrain parts, wherein, parts are arranged in the baseplate zone of self-propelled vehicle in this transmission system, and this device is guided a base plate windstream in this transmission system parts when motor-driven vehicle going.
Background technology
For the boundary temperature of parts in boundary temperature, the especially transmission system of the device of keeping self-propelled vehicle side common general knowledge: when travelling operation, come they are ventilated by device with the windstream mating reaction.
The described device of beginning part is known by DE 43 19 281 A1.In order to cool off parts in the transmission system that is configured to rear-axle differential, be provided with the tabular baffle component of a base plate baffle plate, these parts are provided with deflecting plate.The base plate baffle plate is provided with inlet in the deflecting plate zone in the case, aspirates air flowing from the side by these inlets, and air can reach in the zone between baffle plate and the self-propelled vehicle base plate and also can arrive rear-axle differential thus.
Described an air plate in EP 0 888 957 A2, it is positioned in the upstream of backshaft transmission device.Be configured to baffle
Air plate and coolant air between the deflecting plate of the base plate baffle plate back that is located at self-propelled vehicle on water conservancy diversion direction device to be cooled of being directed to self-propelled vehicle, this device relates to a differential transmitting linkage.
Though can make the base plate windstream directionally deflect in the transmission system on the parts, especially on the rear-axle differential, can not guarantee to conform with destination parts guiding base plate windstream in transmission system according to the above one type of prior art syringe.
In JP 10110812A, describe a kind of self-propelled vehicle, wherein between this diff of the back of rear-axle differential on the travel direction and a Das Reserverad, be provided with a device that constitutes plate, be used for the advective cooling of rear-axle differential.This plate is perpendicular to base plate, laterally arranges with travel direction and is connected with base plate in the zone of end thereon.By this plate make base plate windstream retaining the plate front and be directed to this plate around.In the case the base plate windstream also be directed into rear-axle differential around, make the cooling of this rear-axle differential convection current ground thus.On this device especially disadvantageously: the base plate windstream is blocked in perpendicular to the front of the plate of backplane and takes place thus to flow around the uncontrollable of rear-axle differential, and its consequence is to produce disadvantageous turbulent flow on the aerodynamics.
By DE 103 45 328 A1, DE 103 08 084 A2 and DE 44 29 924 B4 are also known is used for other devices of the transmission system parts of cooler motor-car.
Summary of the invention
Task of the present invention is, improves the device of the described type of beginning part so further, so that the air of large volume stream is guided to parts the transmission system from the self-propelled vehicle base plate, these parts is cooled to convection current particularly well.
This task will solve like this, promptly this device has first director element that separates and second director element that separates, wherein first director element with the base plate windstream towards second director element guiding and directly be fixed in the transmission system guiding of second director element on parts base plate windstream around parts in the transmission system.
On device according to the present invention, the task that first director element is born is: the flow direction that makes the base plate windstream that begins from base plate on not half towards the second director element deflection.Be arranged in the zone of parts in the transmission system and partly surround the task that second director element of parts has in this transmission system and be, make windstream deflection so strongly, so that windstream is deflected and flow around parts in the transmission system.Parts relate in particular to the drive disk assembly of self-propelled vehicle, particularly rear-axle differential in this transmission system.
The structure of two independent director element forms of this device can make each director element designed best aspect the water conservancy diversion condition of its proposition.Based on two independent director elements they are installed on the specially suitable position of self-propelled vehicle in addition.For this position of second director element is parts in the described transmission system, and parts fix in second director element and this transmission system.Being regarded as particularly advantageous for first director element is that this first director element is supported in one or more freeing pipes of exhaust gear, especially fixes with this freeing pipe or these freeing pipes.Described supporting by first and second director element makes the motion respect to one another of these director elements very slight.
When two director elements were configured to guide plate, two director elements structurally can constitute especially simply.By using plate can arrive the optimum shape design of deflecting plate simply.
To make the base plate windstream be transported to second director element best and make the windstream that is directed to be directed to parts in the transmission system in order to accomplish by first director element, first director element and/or second director element preferably are configured to baffle, especially are configured to the thin-wall formed body
This especially has big meaning for the configuration of first director element, because windstream begins following side flow along first director element by base plate, and this windstream is made an effort aspect the flow optimized, make windstream flowing of stratiform occur along first director element.
From the first director element zone viewpoint of flow optimized see be regarded as particularly advantageously be, constitute the body V-arrangement ground design of first director element, it has that a relative base plate windstream is positioned at the base portion of upstream and at downstream and this base portion bonded assembly leg.Windstream is directed on the base portion by the base plate baffle plate of self-propelled vehicle and is directed on the leg by base portion, and these legs are suitable for capitally causing that air-flow layeredly deflects to second director element.Therefore base portion preferably is configured to flat basically and extends to respectively in the leg that is in tilted layout.Particularly advantageously be, each leg is set out by base portion and constitutes with reversing, wherein two legs toward each other towards last sensing.Windstream leading between two legs thus, wherein, two legs are because the configuration that reverses upwards is directed the part of windstream on the side.From base portion, the angle that each leg reverses is especially less than 60 °.
Described configuration by first director element can be carried laminar air stream to second director element.This conveying especially realizes in interval between the parts and second director element or the gap in described transmission system.An ectotropic housing component of parts constitutes in the zone of this at interval preferred hull shape formula by second director element and the described transmission system.Air flows at interval by this, and the lasting deflection of windstream because the configuration of the hull shape formula of second director element reaches, and this air causes the good especially advective cooling of parts, especially rear-axle differential in the described transmission system.
First director element and second director element preferably on the flow direction of base plate windstream one after the other to arrange before and after the small distance very.Force air ground is imported in the described transmission system in the interval between the parts and second director element.First director element and relative its preferred arranged in succession closely on the flow direction of base plate windstream of base plate baffle plate of being positioned at the upstream.Guarantee thus not form significant turbulent flow, guarantee the water conservancy diversion of the stratiform of first director element thus in the downstream of base plate baffle plate.
Further feature of the present invention can be by dependent claims, and following the description of the drawings and accompanying drawing itself draw.
